Description

Pulling and separating mechanism Technical Field The invention relates to a pulling and separating mechanism, which is mainly used in a combing machine and belongs to the technical field of textile machinery. Background The combing machine is a key device for removing short fibers, grass impurities and hair grains in the wool spinning process and improving the straightening parallelism and uniformity of the fibers. The draw-off separating mechanism is one of the core working parts of the combing machine, and the performance of the draw-off separating mechanism directly influences the quality of combed sliver, the sliver making rate and the running stability of the machine. The pulling and separating mechanism needs to effectively lap the fibers carded at this time and the tail ends of the fibers output in the previous period to form a continuous combed fleece, and stably output the lapped fleece to a subsequent drafting device through the variable speed motion of a separating roller. The pulling and separating mechanism in the prior art mostly adopts a mechanical cam and a mechanical differential mechanism to control the variable speed motion of the separating roller, a motion curve is fixed, the adjusting range of the lap joint length is limited and limits the process flexibility, the structure is quite complex, the manufacturing cost of machine parts is high, the maintenance is inconvenient, the process adjustment is complex, and more importantly, the vibration is large and the noise is high during high-speed operation.
